Question 4
Easy

An LED driver in a smart lighting system transfers 780 J of electrical energy when operating at a potential difference of 24 V.

Calculate the total charge that flows through the LED driver.

Use the equation:

energy transferred (E)=charge flow (Q)×potential difference (V) \text{energy transferred } (E) = \text{charge flow } (Q) \times \text{potential difference } (V) energy transferred (E)=charge flow (Q)×potential difference (V)
